Abstract

Abstract

The static performance of the high-performance concrete filled steel tubular flexural members were investigated in order to provide foundation for drawing the relative code of Liaoning Province.On the basis of experimental study on 18 specimens(the cubic compressive strength of the in-filled self-consolidating concrete was 96 MPa),it was found that the mid-span moment-curvature curves could be divided into elastic,elasto-plastic and softening stages.The deflection curve was close to sine curve,distribution of longitudinal strain of the steel tube obeyed the plane section assumption,also,the transversely compressed steel tube had no confinement force to the concrete.The mid-span moment-curvature curves and the deformed models were simulated by using FEM and the calculated results checked well with those of tests.In general,there are no essential differences between high-performance concrete filled steel tubular flexural member and normal concrete filled steel tubular flexural member in aspect of static performance.
